The GRIT Freedom Chair

Meet the all-terrain wheelchair designed at MIT. 

We spent eight years rigorously engineering the most versatile all-terrain chair on the market. We went through dozens of prototypes, continuously improving and perfecting the design with the help of hundreds of wheelchair riders and outdoor enthusiasts.

 

Take it anywhere

The Freedom Chair fits in the trunk. Getting to the trailhead has never been easier!

Easy to push

The lever drive gives you the leverage to handle whatever the trail throws at you.

A mountain bike, for your arms

Every moving part is an off-the-shelf bike part, for easy maintenance and infinite customization.

Built for the trail

The rugged and lightweight steel frame is stable like a tripod, keeping you grounded and in control.

Lever drive

Easy to push. Less shoulder strain. More fun.

Our patented lever drive is easier to push than regular wheelchairs, but is way more powerful. We use the properties of levers to give you the benefits of shifting gears on a bike. This means that the Freedom Chair lets you cruise faster than walking speed on smooth ground, but also gives you the power you need to climb over hills and roll through grass, dirt, and sand. Ready for a break? Pulling backwards on the levers applies the brakes.

 

King of the hill

Grabbing the top of the levers gives you a lot of torque, making it easy to overcome obstacles.

Win the race

Grabbing the bottom of the levers lets you cruise efficiently on sidewalks, bike paths, and roads.

Built for the trail

Finally, a chair that can keep up with you.

The Freedom Chair was designed from the ground up to handle any terrain. The 26” mountain bike tires give you superior traction, especially compared to regular wheelchair wheels. Coupled with our lever drive, it’s an unstoppable combination. The Freedom Chair’s lightweight steel frame is extremely strong and provides a smooth ride over bumpy terrain. The big front wheel rolls over obstacles without getting stuck, and the three-wheeled footprint is stable like a tripod. 

 

Roll over anything

We designed the custom 8.75” rubber front wheel to absorb shocks, distribute your weight, and never get stuck. Best of all? It’s solid rubber, so punctures are a thing of the past.

 

The right tread for the job

The Freedom Chair tires (in the middle below) offer great off-road traction without slowing you down on the pavement. At 1.75" wide, they are almost twice as wide as standard wheelchair wheels (on the left below). While the regular Freedom Chair tires do fine on soft ground like sand and snow, if you're a beach bum or snow bunny, you'll want to check out our Sand/Snow tires (on the right below). At 2.25" wide, they float over the soft stuff.

No road? No problem.

 

 




Take it anywhere 

With quick-release everything, the Freedom Chair packs light.

The Freedom Chair is the first all-terrain wheelchair that’s just as easy to get to the trail as it is to use on the trail.  The wheels, seatback, and footrest are all quick release, enabling the Freedom Chair to fit into the trunk of a small car. We designed it to disassemble in less than a minute, and the more you disassemble the lighter it gets (as opposed to folding chairs, which stay the same weight regardless). The weight of the heaviest part to lift into the car is just 25 pounds.

A mountain bike, for your arms

Easy to use and even easier to own.

Every moving part on the Freedom Chair is an off-the-shelf bike part. This makes maintenance, customization, and repairs easy and inexpensive. Taking care of your Freedom Chair is as simple as keeping the tires inflated and occasionally greasing the chain. Feeling adventurous? Standard bike interfaces make it easy to install custom tires or change the gearing. Need to make an adjustment? Your local bike shop will know just what to do.

Intelligently designed

Eight years of R&D at your fingertips.

We came up with the initial concept for the Freedom Chair in 2008, while we were students at MIT, and we’ve been working on it ever since. We designed it with the help of hundreds of wheelchair riders around the world, and tested it in some of the harshest conditions imaginable: the plains of East Africa, rural Nepal, and Haiti. 


The levers store on the frame, allowing you to move just like in a regular wheelchair. This helps with transfers and using the Freedom Chair indoors.

The adjustable height footrest helps you ensure a comfortable fit in the Freedom Chair. Slots are included to accommodate optional foot straps.

 

The easy-to-use parking brakes keep you locked in place when transferring into and out of the chair.

The pad supports your back, so you can push hard, even without trunk strength.

Pulling backwards on the levers activates the powerful friction brakes, slowing you down.
